Multiple innovations in characterizing piezoelectric materials (2023)
Presentation / Conference
Fotouhi, S., Athanasiadis, I., Shvarts, A., Kaczmarczyk, L., Liu, B., Pearce, C., & Cochran, S. (2023, November). Multiple innovations in characterizing piezoelectric materials. Poster presented at Electroceramics for End Users XII (ECEUXII), Glasgow

Characterisation of piezoelectric materials is a key part. The IEEE standard is the only approach that can produce a full elastopiezodielectric matrix. However, it requires multiple samples. This often involves difficulties preparing the samples for... Read More about Multiple innovations in characterizing piezoelectric materials.

Non-contact characterisation of piezoelectric materials (2023)
Presentation / Conference
Alexandrou, A., Fotouhi, S., Nelson, J., & Cochran, S. (2023, November). Non-contact characterisation of piezoelectric materials. Poster presented at Electroceramics for End Users XII (ECEUXII), Glagow, UK

Piezoelectric materials play a key role in various technological applications owing to their unique elastic-piezoelectric-dielectric (EPD) properties, often represented in matrix form. Traditional methods for obtaining these properties, as defined by... Read More about Non-contact characterisation of piezoelectric materials.
